Foldable desk

ABSTRACT

The present invention provides an improved foldable desk comprising a desk board, and two desk legs, wherein one side of the desk board having a storing trench portion at its central part, and side holes are provided at two sides of two inner parts of the storing trench portion. Two leg trenches are extended respectively from two sides of a central portion of the storing trench portion. The desk legs are confined systematically to an extended shape structure of the leg trenches, and two middle parts of the desk legs are extended outwardly to form arc-shaped parts that are inserted into the corresponded holes of the desk board to form connecting sections so that the desk legs are folded up and stored inside the leg trenches of the desk board to view only half of a size of a side view of the foldable desk.

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates an improved foldable desk's structure, particularly, the present invention relates an improved structure of a foldable desk that can be folded up and stored away easily and conveniently.

2. Description of the Related Art

The conventional foldable desk's structure normally comprises a desk board and foldable desk legs located at one surface of the desk. When the desk is stored away, the foldable desk legs are folded up towards inner parts of the desk to reduce the storage space. The problem of the conventional foldable desk is that once the foldable desk legs are folded up towards the inner part of the desk, uneven side surface of the desk board will occur resulting multiple foldable desks cannot be stacked and stored together. Further, the foldable legs of the conventional foldable desk designs in such that the foldable legs can be folded up easily, but it also easily to be slid off from the desk when it is moved. It result inconvenience to the user. As a result, the present invention is invented to overcome those defaults of the conventional foldable desk.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an improved structure of foldable desk that can be stacked up and stored away in multiple numbers to reduce the storage space. The present invention designs an improved foldable desk that is integrated perfectly that the desk legs are perfectly locked within a bottom part of a desk board without coming off from the desk board.

The foldable desk of the present invention comprises a desk board, and two desk legs, wherein one side of the desk board having a storing trench portion at its central part, and a plurality of side holes are provided at two sides of two inner parts of the storing trench portion. Two leg trenches are extended respectively from two sides of a central portion of the storing trench portion. The desk legs are confined systematically to an extended shape structure of the leg trenches, and two middle parts of the desk legs are extended outwardly to form arc-shaped parts that are inserted into the corresponded holes of the desk board to form connecting portions so that the desk legs are folded up and stored inside the leg trenches of the desk board to view only half of a size of a side view of the foldable desk. When the desk legs are folded up within the desk board, a circumferential portion of the storing trench portion will not protrude outside a circumferential part of the desk board.

Both the forgoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 illustrates an assembly view of a foldable structure of desk in accordance with a preferred example of the present invention, and FIG. 2 is a 3-D view of the assembled foldable desk of the present invention. The foldable desk of the present invention comprises a desk board 1, internal supports 2 and desk legs 3, wherein one side of the desk board 1 provides a storing trench portion 11 at its central part, and a plurality of holes 14 are provided at two sides of the inner parts of the storing trench portion 11. Two leg trenches 12 are extended respectively from two sides of a central portion of the storing trench portion 11, and a hook stand 13 is provided at a middle part of the leg trenches 12.

A hook part 131 is formed respectively at both sides of the hook stand 13, and two sets of middle holes 15 are provided at sides of the middle part of the leg trenches 12. Two inner supports 2 are attached to two inner sides of the storing trench portion 11 of the desk board 1 through screws 21. Side openings 24 and middle openings 25 are provided at the inner supports 2 to correspond with the positions of the holes 14 and the middle holes 15 of the desk 1, and the desk legs 3 is confined systematically to an extended shape of the leg trenches 12 of the desk board 1. Two middle parts 33, located at a middle portion of a stand of every desk leg 3, are extended vertically and parallel to each other, wherein the middle parts 33 of the desk legs 3 are extended outwardly to form arc-shaped parts 34. The side holes 24 of the inner supports 2 are inserted into the corresponded holes 14 of the desk board 1 to form connecting portions, wherein a middle rod 32 is located horizontally in between a central part of the two middle parts 33 of each desk leg 3 to provide a connection of one end of a slant connecting bar 31 that can be bent in one direction. Two upper parallel bars 35 are inserted through the middle openings 25 and reached to the middle holes 15 of the desk board 1 to form a connecting pivot so that the upper parallel bars 35 can be pivoted to another end of the slant connecting bar 31. By using two slant connecting bars 31, the desk legs 3 can be stored and folded up within the inner section of the bottom part of the desk board 1.

FIG. 3 shows a 3-D assembled view of the foldable desk in a stored state. FIG. 4 is a cross-sectional view of the foldable desk in a stored state. FIG. 5 is another cross-sectional view of the foldable desk in a stored state. FIG. 6 is a bottom view of the foldable desk in a stored state. From the drawings, the desk legs 3 are folded up and stored inside the leg trenches 12 of the desk board 1 in such that only half size of side view of the foldable desk is visible. The desk legs 3 are designed in such that they can be unfolded easily from the leg trenches 12. Once the desk legs 3 are folded up, the circumferential portion of the storing trench portion 11 does not protrude outside the circumferential part of the desk board 1 to result a lumpy or uneven surface area. In other words, the surface area of the desk board 1 is appearing and evenly after the foldable desk is stored up. The present invention provides an improved foldable desk that a multiple foldable desks can be stacked up and stored away together to reduce the storage space. The hook part 131 of the hook stand 13 is integrated perfectly within the two middle parts 33 of the desk legs 3 in such that the desk legs 3 are perfectly locked within the bottom part of the desk board 1 without coming off or slid off from the desk board 1.
